Definitions
- Piston engine in particular reciprocating piston internal combustion engine with additional charge control
- the invention relates to a piston engine, in particular a reciprocating piston internal combustion engine with additional charge control according to the preamble of patent claim 1.
- the invention is concerned with the problem of providing additional valves which are more suitable for the generic application.
- This problem is solved in a generic reciprocating piston machine by designing the additional valves according to the characterizing features of patent claim 1.
- An additional valve in the form of a rotating rotary valve used in the intake tract of an internal combustion engine for additional charge control is already known from DE 26 21 362 AI. Due to the lack of division of a charge channel area into two parallel charge channel paths with at least one provided rotating rotary valve provided there, the possibilities for additional charge control are limited. For example, in the case of a charge channel with parallel flow paths that are not parallel in areas and each have an additional control valve, it is not possible to change closing and opening times independently of one another, since their assignment depends on the unchangeable geometry of the rotating slide and the unchangeable geometry of the control edges on the housing Rotary slide valve is dependent.
- the invention is based on the general idea that, by dividing the charge channel into regions in two mutually parallel flow paths, in each of which a rotating rotary slide valve is provided, almost any control options for the charge volume. flow through phase shift of the rotary movement of the rotary valve in the rotary valve to achieve.
- Such a charge control variability according to the invention can in particular not be achieved with a device according to JP 22 41 925, in which an additional valve in the form of a rotary slide valve with two concentrically rotating rotary slide valves is used in an undivided charge channel.
- Embodiments of the invention specifying various possible additional charge controls are shown in the drawing and are described in more detail below.
- Fig. 1 is a schematic, partially sectioned
- Fig. 3 shows a charge channel in a basic embodiment according to Fig. 1, in which, in contrast to the embodiment in Fig. 1 in one of the two Parallel flow paths two rotary slide valves are arranged in series,
- FIG. 1 shows an example of a charge channel of a reciprocating piston internal combustion engine with an intake manifold 1, a charge channel 2 leading into the working space of the internal combustion engine and an area 3 of the charge channel 2 with two flow paths running parallel to one another, in each of which a rotary slide valve 4, 5 is provided as an additional control valve is.
- the connection of the suction pipe 1 to the parallel flow paths within the area 3 of the charge channel 2 is not shown in the drawing.
- the drive of the rotary slide valve within the rotary slide valve 4 and 5 is also not shown.
- the rotary slide valves of the rotary slide valves 4 and 5 can be driven with the number of revolutions of the camshaft 6 acting on a main valve 7 controlling the working space of the internal combustion engine by the crankshaft of the internal combustion engine, not shown.
- the main valve denoted by 7 is / - an inlet valve for the associated working space of the internal combustion engine, in which a piston oscillates in a reciprocating piston engine.
- the rotary slide valves of the rotary slide valves 4, 5 can rotate out of phase with respect to one another and with respect to the phase position of the camshaft 6, for which purpose conventional phase shifting devices known per se must be switched on in the drive.
- the camshaft 6 acts on the main valve 7 via, for example, a lever 8.
- FIG. 2 each schematically show an intake valve lift (V) as a function of the crankshaft rotation angle of an internal combustion engine and the opening and closing times for the two rotary valves (40, 50, 4S, 5S) for an assigned engine cylinder as Working space.
- V intake valve lift
- the representation is such that the numbers entered on the ordinate mean 1 fully open and 0 closed cross section.
- the operating point shown in the diagram in FIG. 2A corresponds to a non-functional state of the additional control valves designed as rotary valves 4, 5. Depending on the design of the suction system, such an operating point may be desired, for example, at the maximum power point.
- the non-functional state of the rotary slide valves 4, 5 as additional control valves means that the rotary slide valves rotate, by means of which there is a flow state within the charge channel 2 as would also be the case with completely missing additional control valves.
- Such a possible behavior of the additional control valves according to the invention is a particular advantage of the invention.
- FIG. 2B shows a state in which an early inlet closing (FES) operating mode is set by phase adjustment of the rotary slide valves 4, 5 with respect to the camshaft 6, in which the charge quantity is only throttle-free is set via the closing times of the rotary slide valves 4, 5.
- FES early inlet closing
- SE ⁇ late intake opening operation
- the rotary slide valves of the rotary slide valve shown in FIG. 3 rotate at half the camshaft speed and are phase-adjustable independently of one another with respect to the camshaft 6.
- a combination of SE ⁇ and FES can be achieved.
- FIG. 4A shows a charge control diagram for a clocked suction process with additional closing after first inflow.
- 4C shows a combination of SE ⁇ and a clocked suction process.
- Any inlet opening times and operating modes can be realized by suitable phase adjustment. Improvements are possible in the various operating modes of piston engines, such as internal combustion engines in two- and four-stroke operation, Otto, Diesel, Gas, Miller, Atkinson, HCCI, free-suction or supercharged operation.
